Changes

A dog was presented as an after-hours emergency for the complaint of acute rectal bleeding. Note the perianal furunculosis, erythema, and exudation. After sedation, fistulous tracts were found 1–2 cm lateral to the anus in positions between 6 and 8 o’clock.

In early autumn you are asked to examine some pedigree Suffolk rams which are in very poor condition (BCS 1.5, scale 1–5). The rams, purchased as yearlings, are grazing permanent pasture and were treated with albendazole (group 1 – benzimidazoles) in late spring and again 2 months later. Many rams have diarrhoea with considerable faecal staining of the perineum. The rams are bright and alert but in much poorer bodily condition than expected. A ram purchased last autumn is especially thin (BCS 1.0) and depressed with pale mucous membranes and slight submandibular oedema. The heart rate and respiratory rates are increased.
